[en] The internal conversion coefficients for the 109 keV M4 transition in ¹²⁵Te are determined employing a mini-orange electron transport for the conversion electrons and a HPGe system for the gamma spectrum, using Normalized Peak to Gamma (NPG) method. The a_m value is being reported for the first time

[en] In this paper a calculation from experimental conversion calculations for gamma transitions in the decay of ¹⁴⁷Nd have been performed

[en] The properties of negative parity states of ¹⁰³Rh have been well accounted for by nuclear models. The M1-E2 mixing ratio involving the internal conversion coefficients of the 53.3 keV transition would be of great help in deciding the exact nature of the 7/2⁺ state of ¹⁰³Rh. In the present paper, α_K has been determined using the normalised peak to gamma method. α_L is being measured for the first time

[en] Orange type configurations of permanent magnets have been used to transport electrons from a source to a detector with many advantages. Some of them are - reduced background, wide energy range, absolute efficiencies as high as 7-10%, large acceptance angles φ, suitable coincide measurements, etc. The size is small and it is quite inexpensive, apart from being easy to operate

[en] The nuclear region around A=100 in which the Rh isotopes lie is interesting particularly because of the variety of nuclear excitations present. The odd-proton ¹⁰³Rh is of particular interest. Single particle and collective excitations in ¹⁰³Rh have been studied

[en] If a h_11/2 state existed as per the systematics observed in the neighbourhood, it must be fed at least from the higher states by weak transitions. A high efficiency gamma and a high transmission conversion electron spectroscopy system would be of great help in looking for the gamma transitions and their corresponding conversion lines, leading to the observation of the h_11/2 state in ¹⁴⁷Pm. Such a careful investigation on the decay of ¹⁴⁷Nd is presented

[en] In the present study, a closer look have been taken at these assignments to the ground state in ²⁵²Es by using a simple phenomenological model that includes the zero-range residual p-n interactions. Under this approach, the bandhead energies of the deformed odd-odd nuclei are calculated using the empirical formula

[en] Mini-orange type electron transporters have been effectively used for both in-beam and off-beam conversion electron experiments. Their effectiveness in enhancing electron detection and simultaneously retarding γ- and δ- ray background had been well documented. Transmission curves obtained experimentally suggest that the peak transmission and the energy range for electron detection are heavily dependent on the two distances, source to magnets(f) and detector to magnets (g), and to a lesser extent, on some other parameters. Consequently, it is desirable to have a knowledge of this dependence before designing the vacuum chamber. MINORSIM - the mini-orange computer simulation code developed, helps to meet these needs

[en] The K, L and M internal conversion coefficients of the 39.76 keV 7/2⁺ → 1/2^- hindered transition in ¹⁰³Rh are measured, using the normalized peak to gamma method. A Mini-orange electron spectrometer and a HPGe detector system have been employed for the study, α_M is being reported for the first time. The present study confirms the systematics of large deviations of experimental ICC of highly hindered high multipole transitions from the theoretical values. (author)

[en] Low-lying two-quasiparticle bandhead energies for the Z=99 odd-odd nucleus ²⁵⁴Es are evaluated using a simple phenomenological model with the inclusion of the residual p-n interaction. Configurations of the intrinsic levels directly fed in ²⁵⁴Es from the parent ²⁵⁸Md are discussed in the light of this model. Our analysis predicts the occurrence of ten K≤5 bandheads in ²⁵⁴Es with excitation energies E_x≤300 keV. Structures of these as yet unidentified low-lying intrinsic levels and their expected locations are discussed in the light of available experimental information. (orig.)
