Search for the decays {eta}{r_arrow}{mu}{ital e} and {eta}{r_arrow}{ital e}{sup +}{ital e}{sup {minus}}
A search for the lepton-family-violating decay {eta}{r_arrow}{mu}{ital e} and the rare decay {eta}{r_arrow}{ital e}{sup +}{ital e}{sup {minus}} yields the following branching ratio ({ital B}) upper limits at a 90{percent} confidence level: {ital B}({eta}{r_arrow}{mu}{ital e}){lt}6{times}10{sup {minus}6} and {ital B}({eta}{r_arrow}{ital e}{sup +}{ital e}{sup {minus}}){lt}2{times}10{sup {minus}4}. This is the first direct search for {eta}{r_arrow}{mu}{ital e}. The measurements were carried out at the SPES2 tagged {eta} facility at Laboratoire National Saturne in the course of a measurement of {ital B}({eta}{r_arrow}{mu}{sup +}{mu}{sup {minus}}). {copyright} {ital 1996 The American Physical Society.}
