Abstract

Relativistic effects can explain the energy shift of - 6 keV reported by Ramayya et al. for the -ray de-exciting the first 2 ⁺ state, at 3368.03 keV, of the ¹⁰Be cluster emitted together with the fragments ¹⁴⁶Ba and ⁹⁶Sr in the ternary fission of ²⁵²Cf; the calculated shift is equal to -6.14 (0.16) keV. An explanation is presented for the apparent absence of Doppler broadening. For the configurations ¹³⁸Xe-¹⁰⁴Zr-¹⁰Be and ¹³⁶Te-¹⁰⁶Mo-¹⁰Be, recently reported by Hamilton et al. , observable shifts of the 3367.43 keV -line are predicted.
