    "abstract": "The differential cross sections of $pD\\to ^3He X$ reactions, where $X=\\eta, \\\n\\eta\u0027\\ ,\\omega, \\ \\phi $, are calculated on the basis of a two-step mechanism\ninvolving the subprocesses $pp\\to d\\pi ^+$ and $\\pi^+n\\to Xp $. It is shown\nthat this model describes well the form of energy dependence of available\nexperimental cross sections at the final c.m.s. momentum $p^*$=0.4-1$ GeV/c$\nfor the $\\eta $ and at $p^*=0-0.5$ GeV/c for the $\\omega $ meson as well as the\nratios $R(\\eta\u0027/\\eta) $ and $R(\\phi/\\omega)$. The absolute value of the cross\nsection is underestimated by an overall normalization factor of about 3 for\n$\\eta, \\ \\eta \u0027$ and by nearly one order of magnitude for $\\omega$ and $\\phi$.\nThe spin-spin correlations are predicted for the reaction ${\\vec D}{\\vec p}\\to\n^3He X$ in the forward-backward approximations for the elementary amplitudes.",
