A first search of excited states double beta and double electron capture decays of 110Pd and 102Pd

A search for double beta decays of the palladium isotopes 110Pd and 102Pd into excited states of their daughters was performed and first half-life limits for the 2νββ and 0νββ decays into first excited 0+ and 2+ states of 5.89×1019 yr and 4.40×1019 yr (95% CL) for the 110Pd decay were obtained. The half-life limits for the corresponding double electron capture transition of 102Pd are 7.64×1018 yr and 2.68×1018 yr (95% CL) respectively. These are the first measurements for 102Pd.
