Inner bremsstrahlung accompanyingβdecay ofPm147

Abstract

The inner bremsstrahlung spectrum associated with the nonunique first-forbidden P decay of Pm was measured employing the magnetic deflection method with a 4.5&& 5.1 cm NaI(Tl) scintillation spectrometer in the energy region 30 -200 keV. The contribution due to the 121 keV source gamma ray line was subtracted by normalizing its peak with that of the 122 keV ' Co gamma ray

Study of the continuous internal bremsstrahlung spectrum from 204Tl by using singular value decomposition

“…For almost all forbidden transition of nuclei, the IB photon intensity spectra in the higher energy region have a problem of rapidly decreasing spectral intensity. Many authors (Babu et al, 1987(Babu et al, , 1985bBasavaraju et al, 1983;Sayibaba et al, 1987;Venkataramaiah et al, 1980;Gundu Rao et al, 1981) could not however explain exactly the deviation between the theory and experiment. We had also worked on IB spectra from different radioisotopes using modern unfolding approach like Gold Iteration Method (Almaz, 2007;.…”

UNFOLDING CONTINUOUS PHOTON SPECTRUM EMITTED FROM 90Sr-90Y IN EQUILIBRIUM

“…Almost all the forbidden transition of nuclei, the IB photon intensity spectra in the higher energy region have a problem of rapidly decreasing spectral intensity. Many authors [16][17][18][19][20][21][22] cannot however explain the deviation between the theory and experiment. This is probably due to detour effects of forbidden transition of nuclei and the detector response function that highly influences the real IB spectra.…”
