The　Schrodinger　equation　with　a　Yukawa　type　of　potential　is　solved　analytically.　When　different　boundary　conditions　are　taken　into　account,　a　series　of　solutions　are　indicated　as　a　Bessel　function,　the　first　kind　of　Hankel　function　and　the　second　kind　of　Hankel　function,　respectively.　Subsequently,　the　scattering　processes　of　K　(K)　over　bar*　and　D　(D)　over　bar*　are　investigated.　In　the　K　(K)　over　bar*　sector,　the　f1(1285)　particle　is　treated　as　a　K　(K)　over　bar*　bound　state,　therefore,　the　coupling　constant　in　the　K　(K)　over　bar*　Yukawa　potential　can　be　fixed　according　to　the　binding　energy　of　the　f1(1285)　particle.　Consequently,　a　K　(K)　over　bar*　resonance　state　is　generated　by　solving　the　Schrodinger　equation　with　the　outgoing　wave　condition,　which　lies　at　1417　-　i18　MeV　on　the　complex　energy　plane.　It　is　reasonable　to　assume　that　the　K　(K)　over　bar*　resonance　state　at　1417　-　i18　MeV　might　correspond　to　the　f1(1420)　particle　in　the　review　of　the　Particle　Data　Group.　In　the　D　(D)　over　bar*　sector,　since　the　X(3872)　particle　is　almost　located　at　the　D　(D)　over　bar*　threshold,　its　binding　energy　is　approximately　equal　to　zero.　Therefore,　the　coupling　constant　in　the　D　(D)　over　bar*　Yukawa　potential　is　determined,　which　is　related　to　the　first　zero　point　of　the　zero-order　Bessel　function.　Similarly　to　the　K　(K)　over　bar*　case,　four　resonance　states　are　produced　as　solutions　of　the　Schrodinger　equation　with　the　outgoing　wave　condition.　It　is　assumed　that　the　resonance　states　at　3885　-　i1　MeV,　4029　-　i108　MeV,　4328　-　i191　MeV　and　4772　-　i267　MeV　might　be　associated　with　the　Zc(3900),　the　X(3940),　the　chi(c1)(4274)　and　chi(c1)(4685)　particles,　respectively.　It　is　noted　that　all　solutions　are　isospin　degenerate.
