Abstract

The

A_{1}

and

A_{2}

transitions, which delineate the

A_{1}

phase of superfluid

{}^{3}{He}

, are measured in magnetic fields up to 3 T over a wide range of pressures. At zero pressure the

A_{1} - A_{2}

splitting is found to be smaller than at melting pressure by a factor of 5. Strong-coupling effects are similarly smaller by an order of magnitude.
